Yeah Cali and Idaho I think they're like the two states that you are unable to get spores to.. Maybe you got a good buddy or a family member that lives out of state and can purchase the spores for you and then send them back to you? Just a thought...
As for if its easy yeah kinda if you read up on it a bit
There's few thread's on here talking about different TEK's etc..
Even Matt had a nice thread going on here with lots and lots of valuable info.
I think the hardest thing is when you do the inoculation of substrate jars, after that you just got to wait for few weeks for the substrate to be colonized by mycelium, you then birth the cakes and you go from there.
Just read up a bit and you be good
